I did some very basic testing with VDO on block devices, and seem to have about 40% to 70% of the original device's performance (only measured throughput), likely based on the data being fed into VDO. Also, fio is not likely the best tool, i.e. dedup performance and ratio will vary wildly, depending on the data being used (common sense). I see a good use case at higher levels, maybe between RBD and whatever consumes it, will try that next.
